XenApp, XenDesktop customers – Client Drive Mapping Does Not Support Files Larger than 4GB

This issue applies to XenDesktop 4.x, 5.x and XenApp 5.x, 6.x


In XenApp and XenDesktop, very large files which have a file size greater than 4GB are not supported with Client Drive Mapping.

When viewing a file which is greater than 4GB using a published Windows Explorer instance in a XenApp Client Mapped Drive, its file size will be incorrectly displayed.

Additionally, copying a file which has a size greater than 4GB using a CDM mapped drive, only a partial file copy will be done, resulting in an incomplete target file being written.


Very large file sizes are not supported with Client Drive Mapping in both XenApp and XenDesktop.
